Tracked down the issue at least to some extend:
We are running into a JAR-Hell because the job-jar uses the typesafe
config package in version 1.3, but flink enforces 1.1.
We are trying to migrate away from typesafe for our configs.
Thanks,
Dominik

This looks at a first glance like you are mixing up some versions of
different modules. Either some Scala version mix, or Flink dependencies
from different versions.
Can you double check that?

Hey,
I'm trying out 1.2 because I need the new Kafka 0.10 connector.
I compiled my job using the SNAPSHOT releases of flink 1.2 and the job
works fine in local mode.
The problem is that deploying the job to our EMR/YARN cluster fails with a

java.lang.VerifyError: Cannot inherit from final class

The job is from my local machine to our EMR cluster. My local machine runs
a Flink 1.2 SNAPSHOT.
Is this some kind of version conflict?
The dependencies for the job are (sbt project):

How can I debug this further?
